摘要:

利用第七次全国森林资源连续清查数据,以回归模型估计法作为乔木林生物量的主要计算方法,以树种含碳率作为生物量转换为碳储量的系数,从单木归并到样地,从样地加权平均至省级区域,估算乔木林碳储量; 以加权平均转换系数估算疏林地、散生木和四旁树的碳储量,以模型法估算竹林、灌木林的碳储量。结果表明: 中国森林植被碳储量主要集中在西南和东北两大区; 乔木林是中国森林植被碳储量的主体; 人工林碳储量在中国乔木林碳储量中比例超过15%; 阔叶树的碳储量和碳密度均大于针叶树。

Abstract:

In this study, we used biomass regression model to estimate biomass of arbor forest, took carbon-included rate in different tree species as the transferring coefficient from biomass to carbon stock, and further summed a single tree to plot and weighted means to province level. The carbon storage of arbor forests in China were estimated based on original data of 7th national forest continuous inventory. In the same time, carbon storage of open forests, scatted trees and "four-sides" trees were estimated by weighted mean conversion factors, and carbon storage of bamboo and shrubbery were estimated by regression model. The results showed that most of the forest carbon storage was distributed in the southwestern and northeastern China. Arbor forests were a main body of forest carbon storage in China. Carbon storage of plantations was more than 15% of total arbor forests in China, and carbon storage and density of broad leaf trees were higher than that of conifer trees.

Key words: forest inventory, biomass regression model, forest vegetation, carbon storage, carbon density
